What are some complications of laser eye surgery?

Very Few: While laser eye surgery (lasik, prk) is very safe, there can rarley be complications that may affect vision. Most commonly, the eye may not achieve perfect vision, and an enhancement may be needed later. Dry eyes can occur and last for several months, and small abrasions may be present for a few days. More rarely, surface skin can sometimes grow under the flap, causing blurred vision.
